A modern operating system like Mac OS X uses disk-writing strategies to make file fragmentation. Let’s get into how to identify whether a Mac is a good candidate or not. Well, as far as just defragging goes, its not really necessary. But, again, not all Macs need to be defragged. There can be a few reasons why a Mac could be slow, but defragging may help. In general, it’s a good idea to defrag Macs or PCs with HDDs about once a month. Defragging also restores unusable capacity by reducing the space wasted between saved data. Select 'About This Mac.' Select 'More Info.' Click 'System Report.' Under the 'hardware' tab, select 'Serial-ATA.' The resulting information will show the storage device's type, make and manufacturer. This unsystematic storage also creates spaces between saved data on the disk that aren’t usable, reducing storage capacity.ĭefragmenting basically reorders the data on the hard disk and bunches those bits together, making it faster and more efficient to access save files. Here’s how to find out: Pull down the Apple menu. This creates inefficiency, as the mechanical arm accessing a file must move to multiple sectors to collect the various bits of data a computer needs to read and open it. Over time, the data for a saved file becomes fragmented, meaning parts of the file are stored on different sectors of the disk. Hard disk drives (HDDs) store data on a spinning platter that’s divided into sectors. To check the status of all currently available drives, type defrag in the search box and then click Defragment and Optimize Drives from the results list.
